It's 200 megs currently:
memory_limit 200M 200M
You can look over the php settings by going to
www.tthlabel.com/test.php
thats the phpinfo() script that just shows you what the php info is.
I haven't installed or changed anything in probably 2 - 3 weeks, this just suddenly started happening out of the blue. I'm on a VPS, not a regular shared host. VPS is still shared, but I have dedicated resources. I only get 150 - 200 unique visitors a day and have a little over 2000 registered. Most of which were converted from a old post nuke site and aren't even active. There are probably 500 - 600 active users. I did check server health when this error goes on, and at the highest it reports that I have 40% memory used and 60% free.
I tried doing it again just to test, the manual prune in the admin panel, same result, out of memory. I currently have this much memory available:
Memory Used 40.8 %
Swap Used 0.21 %
Server Load 0.07 (8 cpus)
Through my WHM pannel my entire server is in the green, showing no memory running out. My php info file says 200m max limit.
